The ‘Y’ is a bit tighter, and a good fit (pun intended) for the Macbook. Intel’s ’S’ series processor — the one many believe will be included in the Macbook Pro — hasn’t been detailed.

But Intel’s new chipsets are beastly. It says Kaby Lake architecture provides 19 percent better performance for Web browsing compared to Skylake, and 12 percent gains overall. Intel also says you’ll get nearly 10 hours of 4K video playback, and processing a 4K video is up to six times faster than with existing chipsets.

This doesn’t mean the Pro won’t have Kaby Lake, or that it’s delayed beyond the original timeline. Really, we don’t know when the Pro is actually coming, though it’s widely believed Apple will announce it in October.
